While troubleshooting your computer, follow these safety guidelines:

■

Never remove your computer case cover while your computer is turned 
on and while the modem cable, network cable, and power cord are 
connected.

■

Make sure that you are correctly grounded before accessing internal 
components. For more information about preventing damage from static 
electricity, see 

.

If you have problems with your computer, try these things first:

■

Make sure that the AC power adapter is connected to your computer and 
an AC outlet and that the AC outlet is supplying power.

■

If you use a power strip or surge protector, make sure that it is turned on.

■

If a peripheral device (such as a keyboard or mouse) does not work, make 
sure that all connections are secure.

■

Make sure that your hard drive is not full.

■

If an error message appears on the screen, write down the exact message. 
The message may help eMachines Customer Care in diagnosing and fixing 
the problem.

■

If you added or removed peripheral devices, review the installation 
procedures you performed and make sure that you followed each 
instruction.

■

If an error occurs in a program, see the program’s printed documentation 
or the online help.
